Grafex - Model CG CG -Corrugated Gaskets
Corrugated gaskets CG CG are manufactured from a core of profiled metal plate in order to ensure the rigidity and durability of the gasket. The shape of the profile and the thickness of the gasket depend on the diameter and width of the gasket. Graphite layers can totally cover the metallic profile or, by request, just the inside part so that the gasket could also have a centre ring.
